Re: Locking the Keyboard

Here's how I did this:

The screen wasn't a subfile but was instead an array.   The entry fields 
were fixed across the bottom of the screen.  As the user filled the fields 
for one record and entered out of the last field, the line was processed, 
the data was validated, the record was written/updated, and an array of 14 
elements was moved to an array of 13 elements (so that array element #1 
fell off).  Then the 13 element array was moved back to the 14 element 
array.  Then the new data was written to the 14th element and the array 
written back to the screen.  The effect created was that the user always 
entered in the same place, helping with eye conflict issues, and the data 
entered seemed to be rising up the screen and off.  It was a pleasing 
effect for the user.

That was on a Sys/34 when memory was a concern.  Today I'd want to do the 
same thing but work it someway so the user could scroll the file back, and 
select a line to put back in the box for editing.

The nice thing about this solution in my mind is that the bell only rings 
when validation fails, and pagedown/up is not a factor.

This is a modification of the idea you put forward, but I  had the feeling 
you made the post because you weren't entirely comfortable with the user's 
plan?

        Subject:        Locking the Keyboard

Hi everyone,

I believe that this question would have been raised in this forum, but
I would appreciate your little time in helping me with a suggestion.

I have an input subfile that has 6 fields (all numeric). The control
part has two input fields. The user wants to enter the control fields
and automatically go into the subfile area and keep entering the values
into the subfile. User never looks at the screen while entering the
data. When the user enters the last record, they want the keyboard to
be locked with a beep sound. This will help them from entering further
values and they can press either enter (to confirm) or pagedown to
start entering fresh set of records in the subfile. The subfile is
initialized with 1000 records and there are about 18 records displayed
on the screen. Hence when the user presses pagedown the control does
not come into the program.

I thank everyone in advance for a supportive suggestions.

Regards
ChetanP
